Back-analysis of sprayed concrete lined (SCL) tunnel junctions at Liverpool Street Crossrail station
( Elsevier , 2023 , Article)Sprayed concrete linings (SCL) offer a versatile method of tunnel construction, particularly in regard to forming junctions since the lining acts as a shell structure which can redistribute the stresses around the opening ... -
Comparing eurocode 2 prestress loss estimations to strains measured on a pretensioned bridge beam
( CRC Press/Balkema , 2019 , Conference)The implementation of Eurocode 2 (EC2) for the design of concrete structures in South Africa in the near future is pending and necessitates refined understanding of EC2’s prediction models; including prestress losses and ... -
Development of a new excavation technique for centrifuge testing in sand
( CRC Press/Balkema , 2021 , Book chapter)Even though shaft excavation is a key part of tunnelling projects in large cities, many uncertainties about their actual performance still exist in practice and only very few case studies have been reported in the literature. ... -
Development of a three-dimensional staged volume loss tunnelling method in the centrifuge
( ICE Publishing , 2019 , Article)Conventional assessment of tunnelling-induced settlement focuses primarily on transverse profiles given the transitional nature of the longitudinal settlement profile. This approach thus relies on the commonly made assumption ... -
Geosynthetic-reinforced soils above voids: Observation and prediction of soil arching
( Elsevier , 2021 , Article)The assumption with the biggest impact on the design of geosynthetic-reinforced soils above voids is the presence and degree of soil arching, which affects the predicted applied stress on the geosynthetic. A series of ... -
Pervasive Fibre-optic sensor networks in bridges: A UK case study
( CRC Press/Balkema , 2018 , Conference)Integrating fibre-optic sensor networks in a newly-constructed infrastructure assets enables datadriven performance assessment during its construction and throughout its operational life. As part of a multimillion pound ... -
Simulation of wellbore construction in offshore unconsolidated methane hydrate-bearing formation
( Elsevier B.V. , 2018 , Article)The unconsolidated nature of offshore methane hydrate-bearing formation poses challenges to sustainable methane gas production as the weak formation is susceptible to disturbance during wellbore construction. This could ... -
The role of statistics in data-centric engineering
( Elsevier B.V. , 2018 , Article)We explore the role of statistics for Big Data analysis arising from the emerging field of Data-Centric Engineering. Using examples related to sensor-instrumented bridges, we highlight a number of issues and challenges. ... -
The synthesis of data from instrumented structures and physics-based models via Gaussian processes
( Academic Press Inc. , 2019 , Article)At the heart of structural engineering research is the use of data obtained from physical structures such as bridges, viaducts and buildings. These data can represent how the structure responds to various stimuli over time ...
